[0051] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0052] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show the layers related to the present invention and are not drawn according to the number, shape and size of the layers in actual implementation. In actual implementation, the type, quantity and proportion of each layer can be changed arbitrarily, and the layer layout type may also be more complicated.

[0053] In the following description, numerous details are set forth to provide a more thorough explanation of the embodiments of the present invention; however, it is apparent to one skilled in the art that the embodiments of the present invention may be practiced without these specific details.

[0054] Figure 1 This is a structural diagram of a power supply and distribution control system based on a drone command station shown in one embodiment of the present application. Figure 1 As shown, the power distribution control system in this application is generally composed of two parts: a ground intelligent power distribution center (in the dotted box) and a remote control panel. The main function of the ground intelligent power distribution center is hardware loop control, and the remote control panel controls the output of the ground intelligent power distribution center through the RS485 serial port.

[0055] See also Figure 1 The power supply and distribution control system in this application includes a main power input terminal (for Figure 1 AC220V equipment input 1), air conditioner power input (for Figure 1 AC220V air conditioner input 1), UPS power supply, first detection module ( Figure 1 3U4A module set in the input line of the main power supply), the second detection module ( Figure 1 3U4A module installed on the input line of the air conditioner power supply), main control module, working mode switching module (including AC contactors KM01, KM02, KM03), UPS selection switch, main power output module, air conditioner power output module, display, indicator light, buzzer, etc.

[0056] The structure and principle of each module are described as follows:

[0057] (1) Main power input terminal, used to connect to the 220V main power supply;

[0058] (2) Air conditioning power input terminal, used to connect to 220V air conditioning power supply;

[0059] (3) UPS power supply, used to provide uninterruptible backup power;

[0060] UPS stands for Uninterruptible Power Supply, which is an uninterruptible power supply with an energy storage device.

[0061] (4) a first detection module, provided on the input line of the main power supply, for detecting the voltage signal of the main power supply;

[0062] (5) a second detection module, provided on the input line of the air conditioner power supply, for detecting a voltage signal of the air conditioner power supply;

[0063] The first detection module and the second detection module have the same structure, both of which adopt the structure of voltage transformer + follower circuit. Figure 2 This is a circuit diagram of a voltage transformer in one embodiment of the present application. Figure 3 FIG. 1 is a circuit diagram of a follower circuit in an embodiment of the present application, as shown in FIG. Figure 2-Figure 3 As shown, the voltage transformer includes a coupling coil, the primary side of the coupling coil is connected to the input end of the main power supply or the air conditioner power supply, and the secondary circuit of the coupling coil is used to output the detection voltage; multiple resistors are used in the secondary circuit for load matching and current limiting.

[0064] The output end of the follower circuit is used for the reference voltage; the secondary side of the voltage transformer and the output end of the follower circuit are connected to the same detection end of the main control module to superimpose the reference voltage and the detection voltage into a detection signal and send it to the detection end of the main control module; and the voltage value, frequency and phase of the detection signal are detected by the main control module.

[0065] The reference circuit uses resistors to divide the voltage and an LM358 op amp to form a follower circuit, generating a 1.65V reference voltage. A voltage transformer, used as a voltage acquisition element, isolates the source signal from the detection signal. The sampled AC signal is superimposed on the reference voltage to generate a sinusoidal signal exceeding 0V. This sinusoidal signal serves as the detection signal and is output via a 485 interface to the subsequent main control module for testing.

[0066] (6) A main control module, connected to the first detection module and the second detection module, is used to compare the input voltage with the preset normal voltage value. When the input voltage is within the preset voltage range, it is judged to be normal. At this time, the main control module controls the contactor to be turned on through the relay output interface. When the input voltage exceeds the preset voltage range, the main control module controls the contactor to be turned off to implement the over-voltage and under-voltage protection function of the input power supply. The specific judgment and control logic is as follows:

[0067] (6-1) When the value of the voltage signal of the main power supply is outside the preset voltage range and the value of the voltage signal of the air-conditioning power supply is within the preset voltage range, a first switching signal is output; the first switching signal is used to switch the output power supply to the air-conditioning power supply.

[0068] (6-2) When the values ​​of the voltage signal of the main power supply and the voltage signal of the air-conditioning power supply are both outside the preset voltage range, where being outside the voltage range may mean not reaching the voltage range or exceeding the voltage range, a second switching signal is output; the second switching signal is used to switch the output power supply to the UPS power supply.

[0069] (6-3) When the value of the voltage signal of the main power supply is within the preset voltage range and the stability duration exceeds the first duration, a third switching signal is output; the third switching signal is used to switch the output power back to the main power supply when the main power supply returns to normal. The value of the voltage signal of the main power supply is within the preset voltage range, which means that after the main power supply returns to normal, the value of the voltage signal of the main power supply is within the preset voltage range. During normal operation, the value of the voltage signal of the main power supply is always within the preset voltage range, and no action is performed.

[0070] (7) a working mode switching module connected to the main control module, the main power input terminal, the air conditioner power input terminal, and the UPS power supply, configured to switch to the air conditioner power supply for output power based on the first switching signal, and to switch to the UPS power supply for output power based on the second switching signal;

[0071] The working mode switching module includes three AC contactors: the first AC contactor KM01, the second AC contactor KM02 and the third AC contactor KM03;

[0072] One side of the first AC contactor KM01 is connected to the main power supply, and the other side of the first AC contactor KM01 is connected to the first switching terminal of the UPS selection switch; one side of the second AC contactor KM02 is connected to the air-conditioning power supply, and the other side of the second AC contactor KM02 is connected to the first switching terminal of the UPS selection switch; the second switching terminal of the UPS selection switch is connected to the UPS power supply, and the common end of the UPS selection switch is connected to the main power supply output module; one side of the third AC contactor KM03 is connected to the air-conditioning power supply, and the other side of the third AC contactor KM03 is connected to the air-conditioning power supply output module.

[0073] When both input power supplies are normal, the main control board controls contactors KM01 and KM03 to be turned on. At this time, the air conditioner input and device input respectively power their respective devices.

[0074] When a device input fails, the ground-based intelligent power distribution center system automatically disconnects the J01 relay, cutting off power to KM01. After a 0.1-second delay, the J02 relay opens, controlling KM02 to connect. At this point, the load on the device line is powered by the air conditioning line input. When the device line input returns to normal and the voltage stabilizes for 2 seconds, KM02 disconnects. After a 0.1-second delay, KM01 reconnects, implementing automatic input power selection.

[0075] When the equipment input and air conditioning input fail at the same time, KM01, KM02, and KM03 are all disconnected, the equipment line is powered by its own UPS device, and the air conditioning line is powered off.

[0076] The first AC contactor KM01, the second AC contactor KM02 and the third AC contactor KM03 are controlled by a main control module, which includes a switch output circuit. Figure 4 Schematic diagram of the circuit structure of the main control module in one embodiment of the present application. Figure 5 FIG. 1 is a structural diagram of a switch output circuit in an embodiment of the present application. Figure 4-Figure 5 As shown, the main control module in this application includes an MCU and three relays (a first relay J01, a second relay J02, and a third relay J03). The MCU controls the relays through a switching output circuit, thereby controlling the first AC contactor KM01, the second AC contactor KM02, and the third AC contactor KM03.

[0077] Specifically, the switching output circuit includes three optocouplers (Q1-1, Q1-2 and Q1-3). The primary sides of the three optocouplers are all connected to the general IO pins of the MCU. When the general IO pins of the MCU output a low level, the primary side of the optocoupler forms a voltage difference with VCC, which causes the diode to emit light after being turned on.

[0078] The secondary sides of the three optocouplers are connected to the control sides of the first relay J01, the second relay J02, and the third relay J03, respectively. After the diode in the optocoupler emits light, the secondary side of the optocoupler is turned on, charging the coil in the relay to form a magnetic field attraction switch, thereby achieving control of the relay.

[0079] The load side of the first relay J01, the load side of the second relay J02, and the load side of the third relay J03 are used to output switching values, respectively controlling the on / off states of the first AC contactor KM01, the second AC contactor KM02, and the third AC contactor KM03. The relay switches are all housed in sockets, which allow for quick and easy connection of the first, second, and third AC contactors KM01, KM02, and KM03, thereby controlling the AC contactors.

[0080] (8) a UPS selection switch connected to the main control module and the UPS power supply, configured to switch to the main power supply for output power supply based on the third switching signal;

[0081] The UPS selector switch is used to control the UPS status. In this application, a UPS input status detection module is also provided to detect the UPS operating status. The UPS input status detection module is connected to the main control module. When the second switching signal is executed, the UPS main power output module needs to be switched to the connected state.

[0082] Figure 6 FIG. 1 is a structural diagram of a UPS selection switch in an embodiment of the present application. Figure 6 As shown, the UPS selection switch includes a first normally open contact and a second normally open contact.

[0083] The input end of the first normally open contact is connected to the main power supply as a first switching terminal, or the input end of the first normally open contact is connected to the air conditioner power supply as a first switching terminal;

[0084] The input end of the second normally open contact is connected to the UPS power supply as a second switching terminal;

[0085] The output end of the first normally open contact and the output end of the second normally open contact are connected to the main power output module as a common end.

[0086] The two input power sources pass through the two sets of normally open contacts of the transfer switch. When the transfer switch is in the online position, contacts 1, 2, 5, and 6 are closed, and the uninterruptible load is powered by the UPS. When the transfer switch is in the bypass position, contacts 3, 4, 7, and 8 are closed, and the uninterruptible load is powered by the AC220V input. When the transfer switch is in the off position, the power supply to the uninterruptible load is disconnected.

[0087] (9) A main power output module, connected to the working mode switching module and the UPS selection switch, for supplying power to the UAV command and control station.

[0088] The main power output module is the functional module that powers the drone control station in this application and includes a multi-way power supply control switch. The switch control still uses the MCU + relay + AC contactor method, which will not be repeated here.

[0089] like Figure 1 As shown, the power supply equipment of the main power output module includes cabinet 1, cabinet 2, link seat, lighting, flight seat 1, flight seat 2, task seat 1, task seat 2 and 24V DC power supply, among which the 24V DC power supply is realized through the DC-AC module of the equipment.

[0090] (10) An air-conditioning power output module, connected to the air-conditioning power input terminal, for providing power to the air-conditioning system.

[0091] The air conditioning power output module primarily provides power to the air conditioning system within the venue and includes a multi-way power supply control switch. The switch control still uses the MCU + relay + AC contactor method, so I will not elaborate on it here.

[0092] like Figure 1 As shown, the power supply equipment of the air-conditioning power output module includes air-conditioning, sockets, antenna upgrade platform, lifting rod, sliding roof, front electric seats and rear electric seats.

[0093] In addition, in some cases, the air-conditioning power supply may have abnormal conditions alone. Therefore, the main control module is also used to disconnect the third AC contactor KM03 when the value of the voltage signal of the main power supply falls within the preset voltage range and the value of the voltage signal of the air-conditioning power supply exceeds the preset voltage range; when the value of the voltage signal of the air-conditioning power supply recovers to fall within the preset voltage range and the stable time exceeds the first time length, the third AC contactor KM03 is closed.

[0094] When the air conditioning input fails, the ground intelligent power distribution center system automatically disconnects the J03 relay, thereby cutting off the power supply to KM03. KM03 will be reconnected after the air conditioning circuit input returns to normal and the voltage remains stable for 2 seconds.

[0095] (11) Main control module power supply circuit

[0096] In addition, in order to ensure the stable and continuous operation of the ground intelligent power distribution center system, this application needs to provide a stable and reliable power supply for the main control module.

[0097] Figure 7 This is a structural diagram of the power supply circuit of the main control module in one embodiment of the present application, such as Figure 7 As shown, the main control module power supply circuit in this application includes: relay module 1, relay module 2 and AC-DC module. The two input ends of relay module 1 are respectively connected to the air conditioner power supply and the main power supply, and the two input ends of relay module 2 are respectively connected to the output end of relay module 1 and the UPS power supply;

[0098] Relay module 1 is used to output the air conditioner power supply first, and output the main power supply when the air conditioner power supply is abnormal;

[0099] Relay module 2 is used to give priority to outputting UPS power, and outputting air conditioning power or main power when UPS power is abnormal;

[0100] The output end of the relay module 2 is connected to the AC-DC module, and the AC-DC module is used to provide a DC power supply to the main control module.

[0101] Specifically, the 220V input from the air conditioning circuit and the 220V input from the equipment circuit are simultaneously connected to relay module 1. The power acquisition module determines the power input. If the air conditioning circuit is powered, the air conditioning circuit is prioritized. If the air conditioning circuit is disconnected, the equipment circuit is used for power.

[0102] The output power of relay module 1 and the UPS 220V input are simultaneously connected to relay module 2. The power acquisition module determines the power input. If the UPS 220V input is available, the UPS 220V input is prioritized. If the UPS 220V input is not available, the output power of relay module 1 is used.

[0103] The power supply is converted into DC12V system control power to ensure the normal operation of the main control module. When any of the three input power sources has power input, the ground intelligent power distribution center system can operate normally.

[0104] In this application, the priority relationship of the ground intelligent power distribution center is: UPS input > AC220V air conditioner input > AC220V equipment input.

[0105] (12) Display screen, including local display screen and remote control screen. Both local display screen and remote control screen are connected to the main control module. The local display screen can display some information and set some settings. The upper and lower limits of voltage are set through the remote control screen controller software. When the voltage is higher than the upper limit or lower than the lower limit, the over-voltage and under-voltage power-off protection function is realized by controlling J01, J02, and J03 and then controlling KM1, KM2, and KM3 contactors. The control logic is the same as the power-off switching logic.

[0106] (13) The sound and light alarm module is connected to the main control module and can sound an alarm when the power input is abnormal.

[0107] In summary, the main functions and beneficial effects of this application can be summarized as follows:

[0108] The core of this solution is the ground intelligent power distribution center, which samples the voltage and current of the dual external power supply lines and transmits the sampled data through the serial port to the ground power distribution control mainboard, which makes judgments and selects power supply.

[0109] The ground intelligent power distribution center uses input and output control circuit breakers to control the on and off of each input and output, and provide short-circuit protection for the load;

[0110] Each output of the ground intelligent power distribution center has a separate leakage current protection function, which is realized by leakage protection. The leakage protection value of each output is 30mA;

[0111] An LCD screen is installed on the panel of the ground intelligent power distribution center, which can display the voltage and current information of the two input power sources and the fault information of the ground intelligent power distribution center;

[0112] The ground intelligent power distribution center is equipped with a remote control touch screen terminal. Through the 485 communication connection, the input power voltage, current, output current of each channel, input and output on / off status and fault information of the ground intelligent power distribution center can be viewed through the touch screen, and the on / off of each output power can be controlled.

[0113] The ground intelligent power distribution center monitors the two input power supplies through the power acquisition module. The sampled data is transmitted to the ground power distribution control mainboard through the serial port. After the ground power distribution control mainboard makes a judgment, it performs over / under voltage protection.

[0114] When the ground intelligent power distribution center fails, the selector switch on the chassis panel can be used to switch to emergency mode. At this time, the ground intelligent power distribution center will automatically open the air conditioning line input and all outputs, and the air conditioning line will supply power to all devices.

[0115] The ground intelligent power distribution center is equipped with an audible and visual alarm on the front panel. The fault can be silenced by clicking the mute button on the panel of the ground intelligent power distribution center;

[0116] The power supply and distribution control system of the UAV command and control station adopts a triple protection mechanism of dual power supply plus UPS power supply, with high integration and good stability.

[0117] When the power supply and distribution control system of the drone command and control station encounters power supply anomalies (overvoltage, power outage, overcurrent, etc.), it can detect and then compare the parameters with the protection parameters of the built-in program, and then control the on and off of the input power to protect the power distribution system and improve the safety of power distribution.

[0118] The ground intelligent power distribution center in the power supply and distribution control system of the drone command and control station adopts a split design, which can realize remote control and is small in size and can be designed for shelf use.

[0119] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art based on the present application are within the protection scope of the present application.
